The U.S. Department of Energy (DOE) has unveiled the Commercial Lighting Solutions for Office webtool. Available free at www.lightingsolutions.energy.gov, CLS for Office provides customizable lighting and control templates enabling building owners to generate more than 30% lighting energy savings compared to office buildings complying with prevailing energy codes.
Liberty Property Trust partnered with Encelium Technologies to reduce overall lighting energy consumption by 60 percent. The real estate investment trust, which owns 77 million square feet of office and industrial space in more than 20 markets throughout the United States and the United Kingdom, used its 31,000-square-foot office building as a pilot demonstration site of Encelium’s highly advanced Energy Control System (ECS) for use in its other properties.
Researchers at the National Research Council Canada – Institute for Research in Construction (NRC-IRC) conducted a study to determine how far, how fast and over what period lighting can be dimmed before occupants notice and are adversely affected. The results suggest a role for dimmable lighting in demand response programs.
WearGuard-Crest, a division of ARAMARK, set an ambitious goal: to replace all the lighting fixtures throughout 280,000 square feet of office, manufacturing, and retail space at its headquarters in Norwell, Massachusetts, just south of Boston. Furthermore, the company wanted the project to pay for itself in energy savings. J&R Wiring, Inc., took up the challenge. After researching the most advanced lighting control systems on the market today, J&R Wiring identified the one technology with the most powerful return on investment (ROI)—DCL® (Demand Control Lighting) from Universal Lighting Technologies.
Glenn D. Hughes, president of Glenn D. Hughes Consulting Associates and the director of construction for The New York Times Company during the design, installation, and commissioning of the new 52-story New York Times Building, last year made news with his announcement that the Quantum total light management system in the building was achieving a 70 percent lighting energy savings.
A breakthrough light management system from Lutron® Electronics Co., Inc., recently installed in a new, landmark Manhattan office tower, is achieving a “stunning” 70 percent energy savings compared to the ambitious energy-efficiency benchmark the building was designed to meet.
Lutron Electronics Co., Inc. introduces the next generation of the Quantum™ total light management system for improved comfort and productivity and the capability to reduce a building’s lighting electricity usage by 60 percent or more.
Principals and associates at The Lighting Practice, a design firm based in Philadelphia, Pennsylvania, have long advocated sustainable design, and have recently had the opportunity to take their own advice. While planning a move that was completed in June 2007, they designed tenant improvements incorporating energy saving lighting controls that exceeded code requirements and let them demonstrate best practices to customers.
Associate Principal Julie Panassow and Lighting Designer Pomme Suchato were responsible for lighting the new space, and they selected a lighting control panel, occupancy sensors and daylighting controls from Watt Stopper/Legrand to achieve their goals. They succeeded in reducing the firm’s demand for energy, and set a green example for clients.
What are the benefits of combining advanced lighting control strategies in the same space? Are the energy-saving benefits of lighting controls persistent over time? Can advanced lighting controls be successfully applied to open offices given concerns about jurisdiction conflicts, lighting uniformity, etc.? Can they enhance worker satisfaction? A new office lighting field study addresses these questions. Involving about 90 workers in a real-world open-office environment, the one-year study determined that occupancy sensing, daylight harvesting and individual occupant dimming control worked together in the building to produce average energy savings of 47% while correlating with higher occupant environmental and job satisfaction. The study demonstrates that sophisticated lighting control strategies can be combined successfully to generate persistent, large energy savings in open-plan offices while improving occupant satisfaction with their jobs and workspace.
As part of its mission to promote energy efficiency and innovation for the benefit of its customers, the New York Power Authority (NYPA) gives special emphasis to demonstrating new energy-saving technologies. Along these lines, NYPA installed AddressPro® Digital Dimming—an advanced lighting-control technology—from Universal Lighting in several areas of its main administrative office building in White Plains. This was done as part of the wide-ranging measures NYPA has undertaken in recent years to augment the seventeen-story building’s energy efficiency for lowering electric bills and reducing carbon emissions.
